Windows 10: Windows11 Storage Space has disappeared.

I have two storage spaces connected to a windows 11 laptop. I used One of them for years to backup personal data, and it had grown to 15 TB.

Did you check Windows View update history list to see if KB4568831 has already been installed? I would think it has and that is why you got the message you did.

If you have not run the Storage Spaces troubleshooter there are instructions in the other link on do it manually. What is accomplished in either case is that your storage spaces will be set to read only which will allow you to have access to the data on your storage space drive.

The latter manual steps return the Storage Spaces drive to read/write and run optimization, defrag, and integrity routines. If your install is up to date then you should find the cumulative update KB4568831 installed in history. If you have upgraded to 20H2 then the patch discussed elsewhere to address the issue with Storage Spaces showing as RAW is rolled into the upgrade. In either case the manual optimization, defrag, and integrity routines can be run.

Well, I am attaching a links to MS support site for dealing with issues on Parity spaces. The first is an update issued on July 31, 2020, applies to Win 10 2004 and address an issue with in-memory parity bitmaps that can cause data integrity issues in Storage Spaces. Check to see if your Windows install has this update. If not I recommend that you install it.

After the above update is verified or has been installed then refer to the link below for recovery steps for Storage Spaces cleanup. I would recommend that you follow the Manual steps that follow the troubleshooting outlined in this article. Working through PowerShell with Storage Spaces is far more effective than most other means. If these steps do not resolve the issue for you then short of adding more disks to the spaces I am out of recommendations here.
